g is also affected by the fact that the Earth rotates and an observer on its surface therefore experiences a centrifugal force. We can summarise by saying: (1) If the Earth were a non-rotating perfect sphere, the acceleration due to gravity would be constant. (2) Because of rotation, the Earth is flattened at poles. This affects g in two ways:-
Multifocal motor neuropathy (MMN) is a disease that affects your body's motor nerves. Those are the nerves that control your muscles.
Motor nerve damage is most commonly associated with muscle weakness. Other symptoms may include painful cramps and fasciculations (uncontrolled muscle twitching visible under the skin), muscle atrophy (severe shrinkage of muscle size), and decreased reflexes.n many cases, however, a specific cause cannot be identified. Doctors usually refer to neuropathies with no known cause as idiopathic. Causes of acquired peripheral neuropathy include: Physical injury (trauma) is the most common cause of acquired nerve injury.
